Bruce Cockburn is well known for his outspoken support of environmental and humanitarian causes, and his multi-decade career has yielded 33 records, including his latest, Bone On Bone. This week, he will be inducted into the Canadian Songwriters Hall of Fame alongside another outspoken icon, Neil Young. We spoke with Cockburn about how he came to his ecological worldview, why he wrote iconic songs like "If a Tree Falls" and "If I Had A Rocket Launcher," as well as similar songs on his new record, and we also discuss where he finds hope for the future.

Our second guest is Amanda Lollar, founder and president of Bat World Sanctuary, a wildlife rehabilitation center in Texas. Lollar discusses the efforts of a number of dedicated wildlife rehabbers who took action in the wake of Hurricane Harvey to rescue wild animals in Houston and other impacted areas.

On this episode we take a look at the role technology plays in conservation efforts. First we speak with Topher White of Rainforest Connection, which deploys used cell phones in tropical forests around the world to provide real-time monitoring of forests and wildlife. Its network alerts local communities when illegal logging activities are taking place and can then be stopped, for example.

Then we speak with Matthew Putman, he's the CEO of Nanotronics and an applied physicist with a keen interest in conservation. We discuss some of the technologies that he sees making the biggest contributions to the way we approach conservation, and why he believes these advances can help turn the tide against environmental degradation.
